Approved AC Power Adapter
The CBL is designed to accept voltage input from an external AC-to-DC
power adapter that provides a regulated 6 Volts DC output when plugged
into an electrical wall outlet.
The Texas Instruments model AC-9201 power supply is the only AC-to-
DC power adapter approved for use with the CBL. The use of other
power adapters is strongly discouraged.

Building an External Battery Adapter Cable
To build an external battery adapter cable, you will need a connector, 16-
gauge wire (about 6 feet), and two alligator clips.
Note: At the time of this printing, the Radio Shack Coaxial DC Power
Plug #274-1569 (5.5mm O.D., 2.1mm I.D.) or equivalent is an acceptable
connector.
1. Identify one 3-foot length of the wire as black (ground) and solder it
to the insulated pin of the connector.
2. Identify the other 3-foot length of wire as red and solder it to the
outside of the connector.
3. Connect an alligator clip to the open end of each wire.
